目的：探讨实时剪切波弹性成像（Shear-wave elastography，SWE）联合超声造影（Contrast-enhanced ultrasonography，CEUS）优化乳腺病变BI-RADS分类的价值。方法：对106例女性患者共108个乳腺病变进行SWE和CEUS检查，根据颜色六分法（Ecol）对病灶SWE彩色图像进行色彩评估，运用CEUS 5分法对病灶评分。根据SWE和CEUS结果优化BI-RADS分类。以手术病理结果为诊断金标准，构建受试者工作特征（Receiver operating characteristic，ROC）曲线，比较BI-RADS分类调整前后的曲线下面积（Area under curve，AUC）。结果：BI-RADS分类调整前AUC为0.781，调整后AUC为0.898，两者有显著性差异（P<0.05）。结论：联合应用SWE与CEUS可以明显提高BI-RADS的诊断效能。
Abstract
Objective: To assess the value of shear-wave elastography(SWE) combined with contrast-enhanced ultrasonography(CEUS) in improvement of breast imaging reporting and data system(BI-RADS) categorization. Methods: One hundred and six patients with 108 lesions were examined with SWE and CEUS respectively. Color assessments in SWE was performed using a six-point color score(Ecol), and 5-point scores were assessed for CEUS. A revised BI-RADS classification was assigned based on the combination of SWE and CEUS. The results were compared using the area under the receiver operating characteristic curve(AUC). Results: The AUC of BI-RADS and SWE+CEUS-based BI-RADS were 0.781, 0.898, and significant difference was noted(P<0.05). Conclusion: The combination of SWE and CEUS can significantly improve the diagnostic performance of BI-RADS.
